U.S.E. Alien Aero Seatpost, Carbon and Titanium 27.2 - Medium: 185mm - 240mm
The USE Alien seat post has been the market leader in the lightweight performance sector for six years. The Alien has continually evolved with the latest being the Alien Cyclops. Using a larger (3mm hex key) single bolt central to the clamp design, the Alien Cyclops makes adjustment easier and faster. The new Cyclops design is stronger than ever and is even 5g lighter. The Alien Cyclops has a unique one-key release mechanism that makes re-adjustment as simple as a turn of the hex key.
The position of the rider is critical. The Alien Aero offers the rider up to 20mm layback (10mm more than a standard Alien).
The Alien Aero seat post is designed for the rider who says speed is everything. The Aero post has undergone strict CFD testing to ensure the optimum shape is obtained. Not only is it the fastest post in the range it's got to be one of the best looking.
Before any Aero post leaves our factory, we ensure it passes our NDT (Non Destructive Testing) facility. All this analysis and testing ensures that the Aero post is chosen by champions.
